NFS requires root permissions for mount +2. Use sudo for mount command +3. Check bold-mem permissions: `ls -la /tmp/bold-nfs/target/release/bold-mem` + +**Error: "Connection refused"** + +**Solution:** +1. Restart bold-mem server +2. Check firewall: `sudo pfctl -s all` +3. Try different port: `bold-mem --bind 127.0.0.1:2049` + +--- + +## 5. Success Criteria + +**Phase 1 success criteria:** +- ✅ bold-mem compiles and runs +- ✅ Server listens on port 11112 +- ⏳ macOS mount_nfs connects (requires manual test) +- ⏳ Files visible in mount directory +- ⏳ File reading works +- ⏳ File writing works + +**If Phase 1 succeeds → Proceed to Phase 2 (MarkBaseFS implementation)** + +**If Phase 1 fails → Investigate macOS NFS compatibility, consider libnfs-go fallback** + +--- + +## 6.

Next Steps (After Manual Test) + +**If mount succeeds:** +1. Document mount command that works +2. Note NFS options required for macOS +3. Proceed to Phase 2 (MarkBaseFS implementation) +4. Estimate: Day 2-3 (12-16 hours) + +**If mount fails:** +1. Research macOS NFSv4 compatibility +2. Try NFSv3 mount (vers=3 option) +3. Consider libnfs-go fallback (Go implementation) +4.
